The flow of process data is summarized as follows:
- iFIX reads data from various data sources.
- Internal iFIX database access functions read the data from local or remote databases and transfer it to the requesting software applications. This transfer occurs without any operator interaction. For example, the Scan, Alarm, and Control (SAC) program processes the data and transfers the data to the process database or the Historical Chart presents the data directly to you.
Data may also be written to the data sources by executing these steps in reverse.
